Anthropic has unveiled the open-source Model Context Protocol (MCP), revolutionizing how AI chatbots interact with diverse data systems. MCP enables secure two-way connections using JSON-RPC 2.0, slashing integration time to under an hour. Early adopters like Block, Apollo, Replit, and Codeium are already reaping the benefits. With features like 'sampling' and plans to support SSE, OpenAI’s competing data integration efforts might spark a friendly rivalry in the AI ecosystem.
